Which symptom is commonly associated with peripheral artery disease (PAD)?

Pain or cramping in the legs is a hallmark symptom of peripheral artery disease (PAD). This condition involves the narrowing of peripheral arteries, most commonly in the legs, which leads to reduced blood flow during activities. As a result, individuals often experience intermittent claudication, characterized by leg pain or cramping that occurs during physical activities like walking or climbing stairs. This discomfort typically resolves with rest, as the demand for oxygen decreases.

The other symptoms listed do not align with PAD. Chest tightness is more indicative of heart-related issues, such as angina or heart attacks, rather than peripheral artery problems. Swelling in the arms is often associated with conditions affecting the lymphatic or venous systems. Rapid heart rate, while potentially connected to various cardiovascular conditions, does not specifically correlate with the symptoms of PAD. Therefore, the distinctive pain or cramping in the legs is the key symptom that signifies peripheral artery disease.
